We're preparing to remodel our master bath. The tub is centered under a window in an alcove. Currently, there is a pot light centered in the ceiling above the tub. I got a strange look from one contractor when mentioning I'd like to replace the pot light with a hanging fixture (chandelier). Another contractor told me it would be against code to have a chandelier hanging above a tub. However, I've seen tons of home remodeling shows on TV where the contractor installs such a hanging fixture above a tub. So, what gives?
